1. KEY CONCEPT The biosphere is one of Earth’s four interconnected systems.

3. Atmosphere—air blanketing Earth’s solid and liquid surface

4. Geosphere—geologic features above and below Earth’s surface

6. Climate is the prevailing weather of a region. Climate is the long-term pattern of weather conditions. What conditions would be included? average temperature precipitation relative humidity Key factors shape an area’s climate. temperature sunlight water wind

7. A microclimate is the climate of a small specific place within a larger area.

8. Earth has three main climate zones. The three main zones are the polar, tropical, and temperate climates. Which do we live in? polar climate: the far northernand southern regions ofEarth tropical zone: surrounds the equator temperate zone: the wide area in betweenthe polar and tropical zones

9. 90 N polar temperate tropical temperate polar The angle of the Sun’s rays determine an area’s climate.

11. wind

12. ocean currents

13. Earth’s rotation also has effects on the winds and currents. How?

22. long winters and short summers

24. limited precipitation

26. Polar ice caps and mountains are not considered biomes. Polar ice caps have no soil, therefore no plant community. The climate and organisms found on mountains change as the elevation changes.

27. 1. Which type of growth occurs when a population has unlimited resources and no predators? A. logistic growth B. exponential growth C. S-shaped growth D. population crash

28. Which type of growth occurs when a population has unlimited resources and no predators? A. logistic growth B. exponential growth C. S-shaped growth D. population crash Correct Answer = B Which of the following can cause a population crash? A. a rise in the carrying capacity for a population B. a rise in the emigration rate C. a drop in the immigration rate D. a drop in the carrying capacity for a population

A. a rise in the carrying capacity for a population B. a rise in the emigration rate C. a drop in the immigration rate D. a drop in the carrying capacity for a population Correct Answer = D

30. Review The biosphere is the part of Earth that contains all living things and includes all the ecosystems. Climate is the prevailing weather over an area The uneven heating of the Earth due to its shape, tilt and rotation determines weather. The Earth has six major biomes: Tropical Rainforest Grasslands Desert Temperate forest Taiga Tundra
